Dear Sir/Madam

This letter has been sent to advise you that you can view a copy of the 3i Group plc Report and accounts 2011 on the 2011 Reporting Centre of the 3i Investor relations website at http://reportingcentre.3igroup.com/2011

For your convenience, in respect of the upcoming Annual General Meeting, please find enclosed the Notice of AGM 2011 and proxy card.

If you would prefer to receive an email rather than a letter such as this in future, you can register with the Company's Registrar, Equiniti, at www.shareview.co.uk/clients/3isignup and complete your details.

Benefits of electronic and website communication are:

• quick and easy access;
• it's more environmentally friendly;
• it's more cost effective; and

– you'll find additional information, such as in-depth case studies and a greater breakdown of the portfolio.

Yours faithfully

Kevin Dunn Company Secretary

Your rights

Members of 3i Group plc entered on the Company's ordinary share register at 6.00 pm on 4 July 2011 are entitled to attend and vote at the Annual General Meeting ("AGM"). If you are no longer on the Company's Register of Members at that time, you will not be entitled to attend. If you attend in person, you do not need to complete a proxy form.

What is a "proxy"?

If you cannot or do not wish to attend the AGM, you may appoint someone else to attend for you. That person is known as a "proxy". You may appoint more than one proxy provided each proxy is appointed to exercise the rights attached to a different share or shares held by you. A proxy need not be a member of the Company.

Voting

If you attend the AGM, you may speak and vote at it. If you appoint a proxy, that person can attend, speak and vote on your behalf. If you wish your proxy to vote in a particular way, insert an X in the relevant "For", "Against" or "Abstain" boxes shown on the proxy form. If you do not indicate how you wish your proxy to vote, your proxy will have the authority to vote or abstain as he/she thinks fit on the resolutions. Your proxy will have discretion to vote on any other business which may properly come before the AGM, unless you indicate otherwise. You should note that an abstain vote is not a vote in law and will not be counted in the calculation of the proportion of votes for and against the resolution.

Appointing a proxy

The proxy form makes provision for you to appoint the Chairman of the AGM as your proxy. If you wish to appoint someone else as your proxy, insert the name of that other person in the blank space provided and delete the words "the Chairman of the Meeting or". If you choose to appoint multiple proxies use a separate copy of this form for each proxy, and indicate after the proxy's name the number of shares in relation to which they are authorised to act. A proxy must attend the AGM in order to vote on your behalf. Returning the proxy form will not prevent you from attending and voting at the AGM in place of your proxy or proxies.

Signing the form on your behalf

If someone signs the proxy form on your behalf, you or that person must send with it the authority under which the form is signed. Where the person appointing the proxy is a company, the form must be executed either under seal or under the hand of an officer, attorney or other person authorised to sign on behalf of the company.
